With this sembly; and, arrangement accurate lateral spacing of the Fig. 3 is a fragmentary perspective view of one plates along the lay member is provided, the

' I result being that the plates are precisely. positioned and firmly held in three planes so that all recesses 24 are accurately aligned forreceiv ing the shuttle. Nevertheless, the guide plates are readily and quickly removed by backing off the various screws or fasteners 29 and 3! whereupon new plates may be fitted, which plates are certain to be aligned because they are all stamped from the same die.

Although the stamping process is well adapted to produce a series of identical guides, it will be understood that in its broader aspects the invention is not limited to stamped guides. Any metal working or forming process that produces accurate and uniform results may be employed, such as forging, casting, die casting and combinations of these processes with machining. However, the guide mounting means is particularly adaptable for use with stamped guide plates, and since stamping is a rapid and economical manufacturing process I prefer specifically to use that process to form the guides.

It will be understood that the mode of operation of the invention is independent of the exact configuration of the parts and that various other aligning and locking devices could be used withtachably mounting said guides on said lay assembly, said mounting means comprising longitudinally extending clamp means, said clamp means comprising an elongated, generally U-shaped member, the legs of said member being formed with longitudinally-spaced slots perlongitudinally spaced slots for locating said guide plates in spaced relation along said lay assembly. 4. In a loom for Weaving, a lay assembly, a

. plurality of spaced shuttle guides, a longitudinal pendicular to the member for locating said. guide I plates in spaced relation along said lay assembly, and holes in the base of said member between said slots for the reception of fasteners, and fasteners in said holes connected to said lay assembly for detachably mounting said member and guides.

2. In a loom for weaving, a lay assembly, a

plurality of spaced shuttle gu des, longitudinal r tongue and groove means formed on said guides and lay assembly for restraining said guides against vertical motion, means for detachably mounting said guides on said lay assembly, said mounting means comprising longitudinally extending clamp means formed with longitudinally spaced slots for locating said guide plates in spaced relation along said lay assembly, fastening means for urging said mounting means toward said lay assembly, removal of said fastening means freeing said mounting means and guides.

3. In a loom for weaving, a lay assembly, a plurality of spaced shuttle guides, longitudinal tongue and groove means formed on said guides and lay assembly for restraining said guides against vertical motion, means for detachably mounting said guides on said lay assembly, said mounting means comprisin longitudinally extending clamp means, said clamp means comprising an elongated, generally U-shaped member, the legs of said member being formed with tongue formed on said assembly, said guides being notched to receive said tongue, means for detachably mounting said guides on said lay assembly, said mounting means comprising longitudinally extending clamp means, formed with longitudinally spaced slots for locating said guide plates in spaced relation along said lay assembly, and means detachably clamping said mounting means and guides on said lay assembly.

5. In a loom for weaving, a lay assembly, a plurality of spaced shuttle guides, interlocking means formed on said guides and lay assembly for restraining said guides against vertical motion, means for detachably mounting said guides on said lay assembly, said mounting means comprising a plurality of longitudinally extending clamp means, each of said clamp means comprising an elongated, generally U-shaped member, the legs of said member being formed with longitudinally-spaced slots for locating said guides in spaced relation along said lay assembly,

and apertures in the base of each member for receiving fastening assembly.

6. In a loom for Weaving, a lay assembly, a plurality of stamped shuttle guide plates, means formed on said guide plates and lay assembly for restraining said guide plates against vertical motion, means for detachably mounting said guide plates on said lay assembly, said mounting means comprising a plurality of longitudinally extending clamp means, each of said clamp means comprising an elongated, generally U-shaped member, the legs of said member being formed with longitudinally-spaced slots for locating said stamped guide plates in spaced relation along said lay assembly, and apertures in the base of each member for receiving fastening means connected to sa d lay assembly, fastening means extending through said apertures and connected to said lay assembly, said clamp means being constructed so that said legs clear the lay assembly when mounted thereon.
